Relative Humidity Quite Low in Saigon

The relative humidity is quite low in Saigon the last couple days.  This is something I am just not used to.  I never remember it being this low.  Accuweather says the relative humidity is about 38% now.  The mean is around the mid 70s percent.

Last night my skin, nose and lips were drier then normal.  It actually kept me up part of the night.  I thought it was my air conditioner but when I opened the window, that normal moist air that would rush in was not there.  I kind of feel like I am in a desert right now with the way my nose feels.

I hope this is not part of the normal climate change the Earth is facing.

Anyway else experiencing same problems as me in Saigon?
